摘要:
An object to be checked contains a large number of magnetic polymer elements scattered at random. Each of magnetic polymer elements is made up of an element main body formed of a high molecular material, and magnetic metal powder contained in the element main body. The magnetic polymer elements are integrally incorporated in paper and tangled with the wood pulp fibers of the paper three-dimensionally. In the manufacturing process of the object, a processing apparatus magnetically scans the magnetic polymer elements incorporated in the scanning region of the object while moving the scanning region at a predetermined speed, converts a detection signal obtained by the magnetic scan into a cipher code, and records the cipher code in a code indicator section. In the authenticity checking process, the processing apparatus magnetically scans the magnetic polymer elements once again, and a detection signal obtained thereby is collated with the cipher code recorded in the code indicator section. When the detection signal and the cipher code agree with each other, the object is determined as being authentic.
摘要:
A number of high-permeability magnetic elements are dispersed in a scanning region of a checking object. A core of a processing apparatus is provided with an exciting coil and a sensor coil. When a bias magnetic field is applied to the core, and the scanning region is passed in the vicinity of a gap, the permeability of the gap varies depending on the density of the magnetic elements, so that a magnetic flux passing through the core changes. A detection signal corresponding to the change of the magnetic flux is detected by means of the sensor coil. This detection signal is converted into a cipher code and then recorded in a code indicator section of the checking object. In checking the authenticity of the object, a detection signal obtained by scanning the scanning region by means of the processing apparatus and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object is real when the detection signal and the collation code correspond to each other.
摘要:
An object to be checked has a scanning region which contains a large number of magnetic elements scattered at random. Each of the magnetic elements is made up of an element main body formed of a high molecular material, and magnetic metal powder contained in the element main body. A processing apparatus employed for checking whether or not the object is authentic has a magnetic sensor which is made up of a pair of MR elements and a magnet. The MR elements are arranged side by side in the direction in which the scanning region is scanned. In the manufacturing process of the object, a detection signal which is based on variations in the output ratio between the MR elements is produced, with the scanning region of the object being moved. The detection signal is converted into a cipher code, and this cipher code is recorded in a code indicator section. When the object is checked for authenticity, a detection signal obtained by scanning the scanning region is collated with the cipher code recorded in the code indicator section. When the detection signal and the cipher code agree with each other, the object is determined as being authentic.
摘要:
A pulse generating element formed of a switchable magnetic wire is worked so as to have an arcuate shape such that the ratio R/d between the radius of curvature R and diameter d of the wire in a state free from external force ranges from 65 to 95. This is achieved by subjecting a wire of a ferromagnetic material, such as Fe--Co--V, to drawing-bending work. The pulse generating element, which is obtained by cutting the switchable magnetic wire to a predetermined length, is restricted to a substantially straight state by a retaining member, and undergoes a drastic flux reversal when it is subjected to an alternating field.

A number of bistable magnetic devices are dispersed in a scanning region of a checking object. Each bistable magnetic device is formed of a nonmagnetic material which undergoes a drastic flux reversal attributable to the Large Barkhausen effect when subjected in succession to first and second external magnetic fields of opposite directions. A processing apparatus comprises magnetic generators for generating magnetic fields of opposite directions, a transportation mechanism for moving the checking object at constant speed, and a coil for detecting magnetic pulses, which are generated as the bistable magnetic devices are subjected to the flux reversal, as changes of electromagnetic induction voltage. A detection signal for the scanning region detected by the apparatus is converted into a cipher code and then recorded in a code indicator section of the checking object. In checking the authenticity of the object, the detection signal obtained by scanning the scanning region and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object is real when the detection signal and the collation code correspond to each other.

摘要:
A moving-image processing device (101) synthesizes a first moving image and a second moving image. In the first moving image, a first object is drawn, and accompanied by first-object depth information. In the second moving image, a second object is drawn, and accompanied by second-object depth information. A moving image generator (105) generates a third moving image in which the first moving image and the second moving image are synthesized. A clash determiner (103) serving as an interference determiner refers to the first-object depth information and the second-object depth information to determine whether the first object and the second object in the third moving image satisfy interference conditions. If it is determined that the interference conditions are satisfied, a corrector (106) corrects the second moving image by performing a non-deforming transformation in which the shape of the trajectory expressing movement in three-dimensional space over time is maintained.

摘要:
A moving-image processing device (101) synthesizes a first moving image and a second moving image. In the first moving image, a first object is drawn, and accompanied by the anterior-surface depth of the first object. In the second moving image, a second object is drawn, and accompanied by the anterior-surface depth of the second object. A rear-surface-depth acquirer (102) acquires the rear-surface depth of the first object and the rear-surface depth of the second object. A clash determiner (103) functioning as an interference determiner refers to the anterior-surface depth and rear-surface depth of the first object to obtain an occupancy space which the first object can occupy, and refers to the anterior-surface depth and the rear-surface depth of the second object to determine whether the occupancy space and the second object drawn in certain frames of the second moving image satisfy interference conditions. A corrector (106) functioning as a range setter sets, on the basis of a determination result from the interference determiner, the possible range in which the second object can be positioned without interfering with the occupancy space.
